looking really good !
i can't stand this process... i learned a lot between the caterham and the singer, but damn... it's always such a pain
and i'll tell you what i think Dan told me about the unwrap, if it rather clean, and that there's no overlapping faces then it's good enough. There aren't magic tools anywhere. You always have to struggle making it more straight and linear. But now that the skinners can paint in photoshop using 3D, those easy tools can be a bit more appreciated, which makes our life a little easier...
